why i believe in santa more than i believe in bmi

there exists a ridiculous means to gauge health in this world.  it's complete crap and you're better off believing in santa, the tooth fairy, and the easter bunny. it's called body mass index (bmi).  according to its calculations, if i were to lose 5 more pounds, i would be considered "underweight".  anyone who has seen me will verify that i am anything but underweight but, rather, quite healthy, and losing 5 pounds of fat would only be a good thing.

what is this bmi i talk about?  the body mass index is a measure for human body shape based on an individual's weight and height.  devised between 1830 and 1850, body mass index is defined as the indvidual's body mass divided by the square of their height.  even though the medical community has acknowledged major shortcomings regarding bmi, it is still widely used to determine health.  it shouldn't.

let's do a side-by-side comparison of two individuals.  male #1 is 6'0" tall, weighs 250 pounds.  his body fat is at 10% and he works out in the gym 5 days a week lifting weights.  he has a muscular physique.  male #2 is 6'0" tall, weighs 250 pounds.  his body fat is at 29%, he rarely ever works out and has a heavy build.  both of these men, according to the bmi calculator, are considered obese.  by bmi standards, an individual is considered obese if their score is 30 or greater.  they both have a bmi of 33.9, though obviously extremely different health-wise.

please tell me that the ridiculousness of this assessment makes sense to you now?

don't get caught up in the bmi bs.  pay attention to your weight if you're in an unhealthy range, but don't let that # get to you.  focus on how you feel, how your clothes are fitting, your progress in the gym, and the facts that actually matter...not bogus, nonsensical height/weight ratio categories of underweight, ideal, overweight and obese.

eat clean.  live lean.  live better.  live longer.
